The flame or induction hardening of gear teeth is a sound investment. It increases the life of the gear by about 5 times. By taking the time now you will extend the replacement life of your gears and save valuable downtime in the future.

During motion gear teeth are designed make point contact at the pitch-line. Under load, both rolling contact and deformation take place at this point. Over time the tooth wears, pits, becomes noisy and ultimately needs replacement.

Flame/induction hardening decreases both rolling friction and deformation – the gears also run quieter for longer.

Sprockets are another good example of the increased service life obtained from flame/induction hardening.

All components subject to wear achieve increased life by appropriate heat treatment.
